Overheating 3D- Cooling System - Anti-Rollover Bypass Hose
2005 SeaDoo 3D Basic -
I have an overheating problem with the classic melted T-Joint issue & other pipe joints showing evidence of this. I am going through the cooling hoses, checking integrity & cleaning them out - making sure they are clear of blockages.
Besides flushing I'm also checking free flow & leakage via blowing air into the hoses.
When I got to the Anti-Rollover Hose (see graphic) the top valve was blocked & I could not get any air flow - the water flow is indicated as coming from that valve and into the lower one on the tuned pipe. Having read other posts saying to check the valve itself I removed the valve & there was a load of crud in the valve and the opening which I cleaned out.
My query is this - if I blow air via the bottom valve it flows freely, (as do the other hoses and valves), yet when doing the same with the top valve it doesn't flow at all - II want to make certain that this is correct & the method whereby the anti- rollover hose functions (the flow is not supposed to go backward?) or is this indication of a blockage and possibly my overheating problem??
Thanks for any help or advice in "clearing" this up.

I'm in the exact same position as you're describing. I've just got the ski from someone who hasn't run it in 5 years. About 20 minutes into the first ride the engine cut out because of exhaust gasses leaking into the engine from a melted t-fitting on the exhaust.
Did you manage to resolve the issue and should you be able to blow through the valve you have highlighted.
